If you're like me, you've wanted to do images that DON'T feature people with lips that aren't split down the middle. This LoRA is trained specifically on the concept of lips that are one, continuous, unbroken line. Results may vary, but it definitely helps. This LoRA is trained to work better with "split mouth" in the Negative prompt. If it's still generating split lips, amp up the strength of the negative, like say "(split mouth:1.2)". 1.5 is the highest I've tested it on, so I'm not sure what'll happen if you go higher.
